E09: Insulation for Cold Storage Envelope – Above Green

Requirement Summary

This measure can be claimed if the project improves the U-value, which indicates the thermal performance, of any of these elements of the building:

Exterior walls
Internal walls
Floor slabs
Roof slabs, and
Window Glass

The actual U-values of the respective elements should be entered in the software in the Energy tab. For multiple element types with different U-values, use an area-weighted average.

Note: For exterior walls or roofs with insulation, the measure for ‘Wall Insulation’ or ‘Roof Insulation’ should also be selected in the Materials tab, and the actual insulation type and thickness entered.

Intention, Approach/Methodologies, Potential Technologies/Strategies, Relationship to Other Measures, Assumptions

For details on the above, see similar measure descriptions for Insulated walls, Roofs, Low-e coated glass, and High-performance glass previously described in this user guide.

Compliance Guidance

This measure has several components. To claim any component of this measure, it is necessary to demonstrate that the U-value of that component is better (lower) than the base case as listed in the Key Assumptions for the Base Case in the Design section. If the EDGE default for the improved case U-value is used, then it is only necessary to demonstrate that that component has been or will be installed, and that the U-value of the component does not exceed the base case.

If a user-input U-value exceeds the default improved case value, then it is necessary to confirm that the U-value has been calculated in accordance with the “simple” or “combined” method as previously described in the Approach/Methodologies of related glass and wall measures above.

Design Stage

Post-Construction Stage

At the design stage, the following must be used to demonstrate compliance:

Manufacturer’s data sheets showing the seasonal average U-value for the window (including glass and frame); and
A list of different types of windows included in the design (window schedule).
Construction detail drawing showing the insulation material for walls, roof, and floor. Ideally the detail drawing should be annotated with the U-value; and
Calculations of U-value either using the formula or U-value calculators; or
Manufacturer’s data sheet of specified insulation values.

At the post-construction stage, the following must be used to demonstrate compliance:

Photographs of the glazing units installed;
Purchase receipts and delivery notes for the glazing; and
Manufacturer’s data sheets showing the seasonal average U-value for the glazing (including glass and frame)

Since insulation material will not be visible at the post-construction stage, it must be demonstrated that the insulation material specified at the design stage was delivered to the site. The following must be used to demonstrate compliance:

Photographs of the wall, roof and floor construction at a point when the insulation material was visible; and
Delivery note confirming that the insulation material was delivered to the site; and
Updated calculations for U-value if the thickness and type of insulations have changed from the original design.
